To compare postoperative recurrence rates of pterygium surgery with amniotic membrane transplantation with and without mitomycin C.

To evaluate the efficacy of the sutureless amniotic membrane (AM) patch for the treatment of ocular surface disorders.

To evaluate the efficacy of wide excision of subconjucntival fibrovascular tissue after conjunctivo-limbal autograft of primary and recurrent pterygium.

Ectropion is an eversion of the eyelid due to various causes, and it mainly develops in the lower lid. Usually it shows a slow progression, and it is classified as involutional, cicatricial, paralytic and congenital. Acute idiopathic bilateral lower lid ectropion is very rare; few cases have been reported worldwide, and none have been seen in Korea.

The schwannoma is a tumor originating from Schwann cell proliferation. Schwannoma is a rare disease, making up only 1% of all the tumors that develop in the orbit. Schwannomas usually arise from the choroids or the ciliary body, and occurrence in the conjunctiva is especially rare. Few cases have been reported worldwide, and no cases have been reported in Korea thus far. We report our case along with a literature review.

To compare the recurrence rates and complications with amniotic membrane transplantation (fibrin glue group and suture group), conjunctival autograft and conjunctivolimbal autograft in excision of primary pterygium.

Purpose: To evaluate the efficacy of conjunctivo-limbal autograft after wide excision of primary and recurrent pterygia. Methods: Twenty-one eyes of 18 patients with primary pterygium and 18 eyes of 18 patients with recurrent pteygium underwent conjunctivo-limbal autograft after wide excision of pterygium. All patients underwent follow-up for more than six months. Recurrence rates and complications were evaluated. Results: With a minimum of six months of follow-up, fibrovascular tissue in the excised area, not invading the cornea, was noted in one eye (5.6%) in the recurrent pterygium group but no further surgical interventions for the cosmetic problem were needed. One eye (4.8%) showed wound dehiscence, three eyes (14.3%) showed subgraft hemorrhage, and one eye (4.8%) showed subconjunctival fibrosis at the donor site in the primary pterygium group, while two eyes (11.1%) showed subgraft hemorrhage, and one eye (5.6%) showed Tenon's Capsule granuloma at the donor site in the recurrent pterygium group. Conclusions: Conjunctivo-limbal autograft after wide excision of pterygium can be considered an effective treatment with low recurrence rates for both primary and recurrent pterygia.

We present a case of choroidal osteoma and report a pattern of optical coherence tomography and multifocal electroretinography with a literature review.

To compare the efficacy and safety of fibrin glue and sutures for amniotic membrane transplantation after wide excision of primary pterygium.
